Elwha Water Facilities project is composed of the Elwha Surface Water Intake (ESWI), Elwha Water Treatment Plant (EWTP), construction access improvements, and Area Flood Protection (AFP). These four components are all located adjacent to each other north of the Elwha Dam and south of Lower Elwha Klallam Tribe lands. The ESWI project will include the demolition of the existing intake structure and rock weir, construction of the new facilities including: sheet pile control weir, intake structure, diversion pump structure, fish screen structure; tunnel repair; piping; electrical; mechanical; utilities and site work. The site is located adjacent to the Elwha River, with a significant amount of work being done within the river channel. Construction of temporary diversion dams and de-watering will be part of the work. The work within the river channel and floodplain will be seasonal because of seasonally high river flows. The Elwha Water Treatment Plant (EWTP) is located immediately downstream from ESWI and adjacent to the existing Washington Department of Fish and Wildlife (WDFW) Fish Rearing Channel. It is designed to treat water from the ESWI for use in industrial, municipal, and fisheries applications by removing suspended sediments.
